Studies have shown that pregnant women visit the dentist less often.  Routine dental procedures are safe for the developing baby.  Maintenance of oral health is vital to prevent gingivitis, a disease which can be affected by hormonal fluctuations.  Your dentist can ensure that your oral health is not interfering with nutrient intake and also that untreated gingivitis does not progress into periodontitis.
